I had a similar error when moving some disks around in a case where

The original problem I saw was "invalid vdev configuration" although
other cases reported data corruption. You may also want to check
/var/adm/messages for errors such as:

The problem seems to be caused because the system tries to open your
disk under id1,sd@n50000396b5803dd2/a, then sees the label pointing to
c8t2d0s0, at which point ZFS tries to open *that* disk and stops
because it decides that pool is corrupted (not "bkp1t"). Or vice
versa on the paths.
The solution is to import disks one at a time while making sure no
disk is attached at the old connection position. Then export the
disks one at a time. Finally attach and re-import everything once the
crossed-path disks are cleanly exported.
This does seem like a bug, but hopefully not an issue if you export
the pool rather than just disconnecting.

Hello!
I have a 1-disk pool which i use only from time to time.
Normally i would expect that i can import the pool after installing
the disk again, (on 'cold' machine, boot with --reconfigure) the slot
is not relevant.
Just to check that disk and zfs label are ok, i mounted the pool on a
linux machine, everything is ok there.
On OI i cant import the pool, the "-f" flag does not help.
Details below.
Btw, just to be clear, I had this same error before i tried to import
the pool with linux, so the import with linux is not the origin of
the problem here.
Any hints on how to dig into this further are welcome!
Thanks!
Stephan

Hello!
Thanks for your spending your time!
Yes, i am able to import the pool 'tank' when i leave out the disks of
'bkp1t'.
The issue is, that the zfs import routine should read the zfs labels on
the disks instead on insist on some device path.
And in these cases just see if some other disk (that is not part of a
successfully imported 'online' pool) has the correct zfs label for the
"missing" disk.
No?
Stephan
